Viagra may provide more than a wake-up to a man's sex life – it may help the body's immune system fight cancer, a new study involving mice suggests.

Scientists in Germany genetically engineered mice to develop melanoma, the deadliest form of skin cancer, and found that when these mice were given Viagra in their drinking water, they lived twice as long as untreated mice.

The drug works because it "wakes up" the immune system to fight cancer, said study researcher Viktor Umansky, an immunologist at the German Cancer Research Center, in Heidelberg.
